One of these blades is provided with a central knuckle placed in the free space between two end knuckles attached firmly to the other blade, and one pin engaged in these knuckles ensures the free rotation of one blade as compared to the other. The aforesaid central knuckle comprises, furthermore, a pore that opens into one or more housings into which are engaged plugs provided with jaws fitted with catches that enter into peripheral grooves made in the pin. These jaws take the shape of a cylinder with an outer diameter equal to the inner diameter of the boring of the housings, less twice, at least, the thickness of the catches. |
